The first 4mentioned r50 the same device seen from above and in somewhat smoothing arrangement fllnCtiOnS, 0n the C011- larger scale. traly, in such a relation to the other operations On the frame of the cigar machine is attached of the cigar machine that an automatic smoothing a bracket 2 carrying a tube 3, the interior 19 of out of the heads of the cigars is obtained. which is connected to a suction source not shown The third of the devices shown on the drawings, 55

namely the rotating knife arrangement 18, arranged at the side nozzle 30, consists of knives 18 attached to the outer end of the shaft 13a, on the inner end of which the windmotor 14 is fixed. This knife shaft 13a is ,rotatably journaled in the bearing 25 and is prevented by means of flanges on the shaft resting against both sides of the bearing 25 from moving axially. Inside the Windmotor 14 of the member1 18 is a regulating shutter` 16 arranged in the tube nozzle 30, and a similar regulating shutter 16 is arrangedin the part of the tube 3 lying between the two nozzles 30 and 31. Each of the shutters consists of a round disc 16, the diameter of which is as large as the inner diameter of the tube, and which is provided with pins 27 and 17, by the means of which it is rotatably journaled in the walls of the tube. The upper pin 17 is lengthened outwards and bent in order to form a handle 17a. y

The object and the effect of the devices mentionedis the following.

By` the air current or air currents produced by suction in the suction tube 3, the windmotors and consequently the two smoothing arrangements and the knife arrangement are brought in rotary motion. When the smoothing arrangement 13, 10. placed at the end of the tube 3'is rotating, it also receives from the driving shaft 6 an axially reciprocating movement by means of the parts '7, 8;.9, 5, 26 and 11, so that when a cigar with its head 24 has been brought in known manner to the position shown on Fig. l, the smoothing arrangement approaches the head of the cigar and stops finally in the position shown on Fig. 2, where it formsk the cigar end and then returns to give i place for a new cigar. At the other smoothing ar.

rangement, the cigar head is placed by hand into the head former 1U.

The rotating knives 18 are adapted for making a necessary cut in the wrapper, which for this reason is in a known way brought against the'V knives.

The, speed of the windmotors can easily be regu also possible to have one shutter for each of the two smoothing arrangements.

For producing the suction (or pressure) a special apparatus may be used for each cigar machine, or else a common apparatus for several machines. v

What I claim is:

1. In a cigar machine having a source of suction, a rotatable cigar header member, a suction conduit connected to said source of suction, and an air-rotatable propeller arranged in said conduit and connected to said header member and driven by said source of suction.

2. In a cigar machine having a source of suction, an air-rotatable leaf cutting knife, a suction conduit connected to said source of suction,

`and an air-rotatable propeller arranged in said conduit and connected to said knife and driven by said source of suction. l

3. In a cigar machine having a source of suction, a rotatablel header member, a suction conduit connected to saidsource of suction, an airrotatable propeller arranged in said conduit and connected to said header member and driven by said source of suction, and amechanism for imparting axially reciprocating movements to Said tool.

4. In a cigar wrapping machine having a source of suction,'the combination with a rotatable wrapper handling tool of a suction conduit connected to said source'of suction,l and an air-rotatable propeller arranged in said conduit and connected to said tool and driven by said source of suction.

5. In a cigar wrapping machine having a source of suction, the combination with a rotatable wrapper handling tool of a suction conduit connected to said course of suction, said conduit having an aperture, and an air-rotatable propeller arranged in said aperture and connected to said tool and driven by said source of suction.

6. In a cigar wrapping machine having a source of suction, the combination with a rotatable wrapper handling tool of a suction tube connected to said source of suction, a rotatable shaft mounted axially of said tube and carrying said tool secured to it, and an air-rotatable propeller arranged in Said tube and Secured to said shaft and .driven by saidsource of suction. y
